Take string as input from user by %c and %s and confirm that both the strings are equal

#include <stdio.h> 
#include <string.h>
int main() {  
    char str1[20];
    char *str2;
    printf("enter string \n"); **// using %c  input**
    scanf("%c",str1);
     printf(" string 1  is %s  \n",str1);

  
     printf("enter string 2 \n");
    scanf("%s",*str2); //using %s input
 
     printf(" string 1 and 2 is %c and %s \n",str1,str2);**strong text**

    int a=strcmp(str1,str2); //**comparing both**
    printf("%d",a);
    return 0; 
 }

took input from user using %c and %s then used strcmp for comparing the equality of the strings
